11/13/20231 min read


Restricted mouth opening, also known as trismus, can be a cause for concern. The normal mouth opening for an individual is typically around 35-50mm, which is approximately the width of three fingers. If you find that your mouth opening is less than 25mm, or about one and a half to two fingers, it is important to seek advice and treatment as soon as possible.
Trismus can lead to various difficulties, including problems with swallowing, speech, and stiffness in the muscles of the jaw. It can have multiple causes, such as the eruption of wisdom teeth, infections in the wisdom tooth region, and temporomandibular joint (TMJ) disorders. Identifying and addressing the underlying cause is crucial for effective treatment.
If you are experiencing restricted mouth opening, it is recommended to consult with a dental professional or oral surgeon. They will be able to evaluate your condition and determine the most appropriate course of action. Treatment options may include:
- Wisdom tooth extraction: If the restricted mouth opening is due to the eruption of wisdom teeth, removal of these teeth may be necessary. This can help alleviate the pressure and allow for improved mouth opening.
- Infection management: In cases where an infection in the wisdom tooth region is causing trismus, appropriate antibiotics and other measures may be prescribed to control the infection and reduce inflammation.
- TMJ disorder treatment: If the restricted mouth opening is a result of TMJ disorders, a comprehensive treatment plan will be developed to address the underlying issues. This may include medications, physical therapy, and lifestyle modifications.
It is important to note that self-diagnosis and self-treatment are not recommended in cases of restricted mouth opening. Only a qualified dental professional can accurately diagnose the cause and provide appropriate treatment. Delaying or avoiding treatment can lead to further complications and worsen the condition.
In conclusion, if you are experiencing restricted mouth opening, it is essential to seek professional advice. Trismus can have various causes, and early intervention is key to effective treatment. By consulting with a dental professional, you can receive the necessary evaluation and treatment to alleviate the symptoms and improve your overall oral health.
